3.5.7 Display Own Vector [OWN VECT]
NOTE:
The display of own vector needs the connection of the GPS and the heading
sensor. And it is necessary to set the dimension of own ship and the position of
GPS sensor in service menu to display the vector correctly (refer to 3.5.8).
Procedures 1 Press [OWN VECT] key.
The vector length currently being selected is displayed in the information window at the
upper right or left of the screen only when the kind of information is “OWN SHIP”.
If other information (GPS/ DOCKING/ AIS/ WIND or OFF) is selected, put the cursor on
the button (Fig2.3-11 or 21) and press [ENTER] key.
There are shown 2 vectors, one drawn from the bow and the other one from the stern. The
vector will be straight when the vessel doesn’t turn and curved when the vessel turns.
The accuracy from the vectors are depending on the accuracy from the
(D)GPS sensors.
With longer vectors, the accuracy will be lower.
The vectors are calculated with the situation at that time. When there will be
some changed influence from wind, water current etc., are not shown before
the vessel is influenced by this.
